Cyanobacteria often dominate primary productivity and contribute most of the total biomass in terrestrial aquatic ecosystems of the Polar Regions, as they are able to withstand persistent low temperatures, repeated freeze-thaw cycles, and highly variable light, nutrient and osmotic regimes. To improve our understanding of diversity, community structure and biogeography of cyanobacteria that thrive in such environments, I investigate High Arctic and Antarctic cyanobacterial assemblages using environmental 16S rRNA gene surveys, culturing, and phylogenetic and morphological analyses. This project was part of the International Polar Year Programme MERGE.
This project is in collaboration with Warwick F. Vincent (Centre for Northern Studies (CEN) & Laval University, Canada) and Connie Lovejoy (QuébecOcean & Laval University, Canada).

Cyanobacterial assemblages form benthic mats and films at the bottom of Arctic and Antarctic lakes, streams and ponds of polar ice shelves. Cyanobacterial mats are complex and often multilayered three-dimensional structures with filamentous, exopolymer-producing cyanobacteria being the most common cyanobacterial taxa. They can overcome nutrient depleted conditions via internal nutrient recycling and scavenging systems and therefore proliferate despite the nutrient-poor conditions in the overlying water column that are characteristic of polar aquatic ecosystems. They also contain diverse microbial communities including microbial eukaryotes, however little is known about them. Therefore, I am interested in the microbial diversity of these unique consortia, and the genetic bases for nutrient cycling mechanisms to withstand the harsh conditions of the cryosphere.
The project involves collaborations with Warwick F. Vincent (Centre for Northern Studies (CEN) & Laval University, Canada) and Connie Lovejoy (QuébecOcean & Laval University, Canada), Jacques Corbeil (Laval University, Canada), Brett A. Neilan and Brendan P. Burns (University of New South Wales, Australia).

Cyanobacteria are well known for the formation of blue-green algae blooms and production of toxins. Therefore it is of great interest to study and characterize the phylogenetics of toxin-producing cyanobacteria and genes involved in toxin production.
The project involves collaborations with Brett A. Neilan (University of New South Wales, Australia) and Lenora N.L. Gomes (University of Minas Gerais, Brazil).
